Timemore Chestnut S3 – Hand Coffee Grinder for Espresso and Filter
Buy the Timemore Chestnut S3 in Switzerland: hand grinder with S2C890 conical burr and external adjustment ring for espresso and filter. Bern and Zurich.
One ring, one burr set, every brew method: for espresso the ring sits at just a few clicks, for pour-over further up. The housing is metal, the handle folds in, and the burr set comes out without tools (drop-out system).
What sets the Chestnut S3 apart
External adjustment ring
The S3 is the first Timemore grinder with an external adjustment ring. It sits visibly at the top of the housing, much like the ring on a camera lens. One click equals 0.015 mm, and the numbered scale makes every setting easy to find again.
S2C890 burr set
Timemore designed the S2C890 burr set so that the share in the 200 to 250 µm range drops and the share in the 250 to 400 µm range rises, peaking around 375 µm. According to Timemore, this improves body and sweetness in the cup. The burrs are made of hardened SUS420 stainless steel, six-axis CNC machined, with 58 HRC.
Proprietary bearing system
For the first time, Timemore uses a fully in-house bearing system. According to Timemore, tolerances drop by 20 percent and dimensional accuracy doubles. From the factory, the burr gap at the finest setting (0 clicks) is set to 0.075 mm.
The details in everyday use
Foldable handle
The patented, spring-assisted handle folds against the housing with a pull. This keeps the grinder from tipping over, lets it stand compactly on the counter and fit in a bag.
Silicone base
A silicone base on the underside keeps the grinder steady on the counter.
Metal housing
Timemore builds the housing as an all-metal unibody.

Who it is made for
For anyone who wants to grind espresso and filter with one grinder, at home or on the go. The numbered scale makes recipes repeatable. We measure extraction by weight ratio, with 1:2 as a starting point for espresso, never by time alone. No two shots are alike, because the bean, the humidity and how you feel that day all change. Burr sets are like engines: which one you like best is subjective. Our opinion is one of many.
You will find more hand grinders from Timemore in the Timemore collection, and all models under hand grinders. Electric grinders are under coffee grinders.
If you want to compare grinders and machines side by side, you can book an espresso machine and grinder comparison in the showroom: a reserved hour with the equipment, in Zurich Oerlikon including Timemore. An option, not a requirement. A consultation appointment in the showroom, by phone or online is free of charge.

Tip from the roastery: For espresso from the S3, we start at 1:2 and adjust to taste from there. For dense, chocolatey espresso we use Cozy Chocolate or Nutty Delight, for maximum body Very Nutty. If you are looking for fruity notes in a pour-over, you will find them in Wild Peach. That is our recommendation, one of many.
